One molecule of iodine and two molecules of sodium chloride combines the reaction. How many atoms are in a product

1 answer

To determine the number of atoms in the products of the reaction between one molecule of iodine (I₂) and two molecules of sodium chloride (NaCl), we first need to identify the products of this reaction.

The reaction can be written as:

\[ \text{I}_2 + 2 \text{NaCl} \rightarrow 2 \text{NaI} + \text{Cl}_2 \]

From this balanced equation, we can identify the products produced: sodium iodide (NaI) and chlorine gas (Cl₂).

Now, let's calculate the number of atoms in the products:

  1. Sodium iodide (NaI):

    • Each molecule of NaI contains 1 sodium (Na) atom and 1 iodine (I) atom.
    • From the balanced equation, 2 molecules of NaI are produced, which gives:
      • Sodium: \(2 \times 1 = 2\) Na atoms
      • Iodine: \(2 \times 1 = 2\) I atoms
  2. Chlorine gas (Cl₂):

    • Each molecule of Cl₂ contains 2 chlorine (Cl) atoms.
    • From the balanced equation, 1 molecule of Cl₂ is produced, which gives:
      • Chlorine: \(1 \times 2 = 2\) Cl atoms

Now, let's sum up all the atoms in the products:

  • Sodium atoms: 2
  • Iodine atoms: 2
  • Chlorine atoms: 2

Total atoms in products = Sodium atoms + Iodine atoms + Chlorine atoms = \(2 + 2 + 2 = 6\) atoms.

Therefore, there are a total of 6 atoms in the products.
